Neolithodes


Neolithodes is a genus of king crabs, in the family Lithodidae. They are found in all major oceans, both in high and low latitudes. Although there are records from water as shallow as in cold regions, most records are much deeper, typically, with the deepest confirmed at. They are fairly large to large crabs that typically are reddish in color and spiny, although the size of these spines varies depending on species.
Various sessile organisms such as barnacles are sometimes attached to their carapace and legs, and small commensal amphipods may live in their carapace. They are occasionally the victims of parasitic snailfish of the genus Careproctus, which lay their egg mass in the gill chamber of the crab, forming a mobile "home" until they hatch. Conversely, some juvenile Neolithodes have a commensal relationship with Scotoplanes sea cucumbers. To protect itself from large predators, the young crab hides under the sea cucumber.
The word Neolithodes derives from the Greek neo, meaning new, and Lithodes, a closely related genus of king crab. The name of the latter genus originates from the Latin lithodes, meaning stone like.
